Description

TECHNICAL FIELD

[0001] The utility model belongs to the mixing rubber fast cooling technical field especially, relate to a mixing rubber equipment rapid cooling device. BACKGROUND

[0002] In the rubber production process, rubber needs to be opened by the rubber mixing mill, and the roller body for extruding and mixing rubber on the rubber mixing mill needs to be cooled down during the opening process of the rubber mixing mill. For example, when the roller body temperature is too high, the roller body is cooled down during the production and processing process to avoid high rubber temperature.

[0003] The current cooling method is to pump cold water in the water cooling cavity of the rubber mixing mill equipment to the device to cool the roller body. However, in actual work process, when the roller body temperature is too high and the workshop temperature is too high, the water temperature in the water cooling cavity is very high after several times of cooling. On the one hand, it is difficult to quickly cool the device, and on the other hand, it is difficult to cool when the water temperature is higher than the roller body. Therefore, in actual work process, if the water in the water cooling cavity cannot be cooled, only by pumping new low-temperature water and discharging high-temperature water, the water consumption is very large, causing serious waste of water resources, and a large amount of cooling wastewater is generated.

[0004] In addition, in high temperature weather, such as summer, the water temperature pumped from the water storage tank is also high, which further reduces the water cooling efficiency and makes the device unable to cool down in a short time. Therefore, in actual work process, the device often needs to be shut down when the rubber mixing roller temperature is high, and the roller body needs to be cooled down. Because the roller body works with rubber extrusion during the rubber mixing process, the temperature of the rubber mixing roller will rise again in a short time after the device is restarted.

[0005] Therefore, the traditional cooling method has many disadvantages and is limited in use. INVENTION CONTENTS

[0035] Example 1

[0036] like Figs. 1-3 As shown, a rapid cooling device for rubber compounding equipment includes a cooling system, which includes an evaporator 2 (the evaporator 2 is a conventional evaporator 2 disclosed in the prior art, in which water is contained, and the water is cooled by pumping coolant into the evaporator 2 and utilizing the evaporation of the coolant).

[0037] The outlet of the evaporator 2 is connected to a cold water tank 3, and the outlet of the cold water tank 3 is connected to a water pump 8 that pumps water to the working equipment. The outlet of the evaporator 2 is connected to a compressor 1, the outlet of the compressor 1 is connected to a condenser 5, the outlet of the condenser 5 is connected to a liquid receiver 6, the outlet of the liquid receiver 6 is connected to a filter 7, and the outlet of the filter 7 is connected to an expansion valve 4. The expansion valve 4 has a liquid outlet and a gas outlet. The liquid outlet of the expansion valve 4 is connected to the liquid inlet of the evaporator 2, and the gas outlet of the expansion valve 4 is connected to the gas inlet of the compressor 1.

[0038] Specifically, the evaporator 2 is equipped with a circulating water return pipe 101, the outlet of the cold water tank 3 is connected to a cold water outlet pipe, the cold water outlet pipe is connected to a water pump 8, and the outlet of the water pump 8 is connected to the working equipment through a pump water pipe 102.

[0039] The compressor 1 is connected with a cooling liquid discharge pipe 106, which is connected with the inlet end of the condenser 5. The outlet end of the condenser 5 is connected with a cooling liquid outlet pipe 108, which is connected with the inlet end of the liquid reservoir 6. The outlet end of the liquid reservoir 6 is connected with a cooling liquid filter inlet pipe 107, which is connected with the inlet end of the filter 7. The outlet end of the filter 7 is connected with a cooling liquid filter outlet pipe 110, which is connected with the inlet end of the expansion valve 4. The outlet end of the expansion valve 4 is connected with a cooling liquid low-pressure pipe 105, which is connected with the inlet end of the evaporator 2. The outlet end of the expansion valve 4 is connected with a cooling gas outlet pipe 104, which is connected with the inlet end of the evaporator 2.

[0040] At the same time, the outlet end of the evaporator 2 is connected with a recovery gas pipe 103, which is connected with the inlet end of the compressor 1.

[0041] During operation, the compressor 1 (the compressor 1 is a conventional compressor disclosed in the prior art) compresses the cooling gas into a high-temperature and high-pressure liquid state. Then, the high-temperature and high-pressure cooling liquid enters the condenser 5 (the condenser 5 is a conventional air-cooled condenser 5 disclosed in the prior art) to cool the high-temperature and high-pressure cooling liquid. Then, the high-temperature and high-pressure cooling liquid enters the liquid reservoir 6 through the cooling liquid outlet pipe 108 for appropriate storage and enters the filter 7 through the cooling liquid filter inlet pipe 107 for filtration. When the high-temperature and high-pressure cooling liquid enters the expansion valve 4 through the cooling liquid filter outlet pipe 110 105, the pressure of the high-temperature and high-pressure cooling liquid is reduced in the expansion valve 4. After the pressure is reduced, the temperature of the cooling liquid is further reduced. At this time, the low-temperature cooling liquid enters the evaporator 2 from the cooling liquid low-pressure pipe 105 (at the same time, because the pressure of the cooling liquid is reduced in the expansion valve 4, part of the cooling liquid is gasified into low-temperature gas, which enters the evaporator 2 through the cooling gas outlet pipe 104 and is also used to cool the water in the evaporator 2). Because the pressure in the evaporator 2 is atmospheric pressure, the water in the evaporator 2 is rapidly gasified after the pressure is suddenly reduced, thereby reducing the temperature of the water in the evaporator 2. The gasified gas reenters the compressor 1 through the recovery gas pipe 103 connected to the evaporator 2 for re-compression, thereby realizing the circulation of the cooling gas to generate high-temperature and high-pressure cooling liquid.

[0042] During the process, the water in the evaporator 2 is cooled and pumped into the cold water tank 3, which is pumped to the equipment by the water pump 8. The high-temperature water generated by the equipment is returned to the evaporator 2 again for cooling.

[0043] The structure realizes rapid cooling of cooling water used by the working equipment in a circulating, environment-friendly and rapid cooling speed manner, and the high-temperature water generated during equipment operation is rapidly cooled, and the high-temperature problem of the rubber mixing roller on the equipment is solved with high cooling efficiency.

[0044] In actual work, a valve is installed on the pipeline system according to the existing manner to control the fluid and gas.

[0045] The cooling liquid discharge pipe 106 is connected with a branch pipe 104, and the branch pipe 104 is connected with the cooling liquid low-pressure pipe 105. During work, when rapid cooling is needed, a part of high-temperature and high-pressure cooling liquid is diverted from the branch pipe 104 into the evaporator 2, and the high-temperature and high-pressure cooling liquid is rapidly gasified after pressure drop, and rapidly removes the heat in the evaporator 2. Although the heat removed by the condenser 5 after condensation is less, the emergency cooling is realized.

[0046] Embodiment 2

[0047] As shown in Figs. 1-3 , on the basis of the structure of embodiment 1, in order to realize the cooling effect of high-temperature and high-pressure cooling liquid, the cooling liquid discharge pipe 106 is connected with a pre-cooling mechanism. The cooling liquid is pre-cooled before entering the condenser 5. Specifically, the liquid outlet end of the pre-cooling mechanism is connected to the liquid inlet end of the condenser 5 through a pre-cooling pipe 141.

[0048] The pre-cooling mechanism includes a liquid inlet pipe 13 connected to the cooling liquid discharge pipe 106 through a flange, and the liquid inlet pipe 13 is connected with a shunt pipe 11, and the shunt pipe 11 has a plurality of shunt pipe portions (the shunt pipe 11 is integrally formed on the liquid inlet pipe 13), and the pre-cooling mechanism further includes a flow pipe 142, and the flow pipe 142 has a plurality of flow pipe portions, and the shunt pipe portions and the flow pipe portions are respectively connected with air cooling pipes 12.

[0049] In order to improve the air cooling effect, the shape of the air cooling pipe 12 is a spiral structure. The material of the air cooling pipe 12 is purple copper material.

[0050] The spiral structure increases the air cooling path, and the heat exchange efficiency of the purple copper material is higher, and at the same time, the cooling efficiency is further improved by using the shunt cooling method, and the temperature of the high-temperature and high-pressure cooling liquid is greatly reduced after pre-cooling.

[0051] The flow pipe 142 is connected with a liquid outlet pipe 14 (the flow pipe 142 is integrally formed on the liquid outlet pipe 14), and the liquid outlet pipe 14 is connected with the pre-cooling pipe 141.

[0052] The cooling liquid after pre-cooling enters the condenser 5 from the pre-cooling pipe 141.

[0053] The high-temperature and high-pressure liquid entering the condenser 5 is preliminarily cooled in the pre-cooling mode, the cooling effect of the condenser 5 is increased, and the energy consumption for condensation is reduced.

[0054] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
